Querydsl is a framework that enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files, they can be constructed via a fluentDSL/API like Querydsl. It supports JPA, JDO, Java Collections, SQL via JDBC, Lucene, and Hibernate Search.

The goal of Funani is to solve the management of large image and other media collections in a practical way. To help you find the data you want in big data collections, this software allows you to sort it in many different ways. Advanced queries on dates, locations, events, or people, or more generically categories and tags, allow you to narrow the search quickly. Funani can be thought of primarily as a safe. Every file put into the system remains in the system. It is an additive system, which makes unintended deletion impossible. A maintenance mode can still remove unwanted files, but standard users cannot perform this operation. Funani is also a framework designed for extensibility. When new features are requested, they can be implemented by adding new functionality and leaving the existing system alone. Each feature is completely isolated from others as long as it does not depend on them.

openWebX is yet another object oriented PHP framework that follows the rules of strict separation of code and design. Using new technologies like couchDB or mongoDB as data-backends (with MySQL as fallback) nearly everything is an object. You don't have to write any HTML to get a Web site up and running. If you are developer, you simply "program" your site using PHP. If you are a content editor, you can use the included template system to describe your pages. Output is validated HTML5 by default, with other doctypes to choose from. All design is done by way of CSS. The mootools JavaScript framework is used to implement all kinds of client-side things, like galleries, informative popups, and form checkers.
